If you're buying laptops from Dell save yourself some grief and just go
XP:

I just got Vista Basic on a laptop because it was on fire sale for $300,
Acer 3680, new, Celeron M 430, 512 M RAM.
What they advertise as being on Home and Home Premium is not entirely
true.
For example, Remote Access, Tablet PC and Windows Mobility center is in
Basic. Not that any of these, but its the same as in Ultimate.
Basic has good wifi support. I haven't tried direct cabling yet.
There is a simplified version of Backup that cannot be scheduled but does
the job very well. You can easily get an Open Source alternative for
this as well as stuff not included, but was available in XP Home: Fax,
DVD burner and HD DVD editors. Basic comes with XP Home level Movie
Maker. Acer threw in their version of a backup, and I use that, it makes
bit images too.
Basic has the same kernel as the big versions, but without the bell and
whistles that also needs more horsepower to run, such as Aero.
Now, the other 'features' I don't have I wouldn't even use since 3rd
party work better, e.g. why get BitLocker? I use truecrypt. Why use
Defender? I use Spybot. Why use mediaplayer? I use gmplayer etc., all
freeware.
I have mine configured with the Window Classic Interface, so it looks and
works nearly identical to my XP box, and it works with 512M. In the end,
I got it up to 1G, and its sings better.
